Removal of MCI Bluetooth USB dongle causes hci_hcd Ooop and unusability
of part of USB bus...

2. PROBLEM DESCRIPTION
----------------------

I experienced problem with MCI Bluetooth pc2pc Transceiving key on HP
laptom compaq nc6000 using generic installation of Fedore Core 2. When I
plug in device it is recognized good and all BlueZ utilities working
with it without problem. Here is part of /var/log/messages after device
plug-in:

imro kernel: Bluetooth: HCI device and connection manager initialized
imro kernel: Bluetooth: HCI socket layer initialized
imro kernel: Bluetooth: HCI USB driver ver 2.5
imro kernel: usbcore: registered new driver hci_usb

After unplugging device I got Ooops. See down output of oops.

6. PROBLEM REPLICATION
----------------------

Only what remains to me is have same device and try it plug-in and out.
